Can't wait to learn more of the MC's past with Arson and learn more about his character and personality, we didn't get too much time to interact with him yet, but I already thought he was adorable when he was looking up at the MC and putting cartoons for them lmao, I love the art and I wanna give him lots of head-pats!
Vodka actually have already posted a sneak peak of the canon lore on Tumblr here: https://www.tumblr.com/deathbyfirevn/723507415437426688/so-arson-actually-knew-m...
As for the deeper story, it would be updated in the game! There's no way we would spoil it here!
